Every com port up to 206 showing "in-use" .

I have just installed a new hardware usb com port. Windows assigned it to Com 207. Since I only have 5 ports created by SSDR Cat and 2 other hardware usb ports I am trying to find out what is going on.

When I look at the ports in Device Manager only the Com port pairs that SSDR Cat created and the hardware ports that I mentioned are showing. I tried the procedure to show Hidden or "Ghosted " com ports that Tim posted on the forum. Nothing else shows. The only way I see the ports as in use is to go to Device Manager, click on the ports then look at the properties of a port and go to port settings, advanced and try to reassign the port number. The drop down menu shows all ports up to 206 as "in use".

My computer is Win7 Pro 64 bit. I completely uninstalled all versions of SSDR including DAX and Flex VSP per the instructions in the software users guide. After rebooting the computer all the ports still show as in use.

I have no idea what is going on. I would appreciate any suggestions as to where to start looking.

This is a known issue that I reported several weeks ago. I was told the problem has been duplicated and they are in the process of correcting this issue.

The is part of the response I received:

"The vendor that writes the underlaying driver for FlexVSP ,
FabulaTech, has duplicated the issue and is working to address the
problem , I am changing this to a SW Bug close , look for this defect
number # 4394 in the Release notes of future versions of SmartSDR /
SmartCAT"...

I downloaded a program called COM Name Argiter Setter that helps me manage the ports until this issue is resolved...I hope this helps you...

So this is the issue. Whenever a new com port is defined in Windows, it is marked in the registry as "in use". The VSP driver has an acknowledged defect where it is incorrectly modifying the registry to mark com ports "in use" when they are not and FlexRadio is waiting for a fix for that issue as noted above.

To fix the condition to unmark unsued ports are in use, you have to modify the Windows Registry, which we do not recommend doing. There is a program that you can use to do this for you and remove most of the risk associated with modifying the Registry called COM Name Arbiter Setter V0.7 (http://www.uwe-sieber.de/misc_tools_e.html#arbiter). It has to be run as Administrator to modify the registry.

When you run it, only leave the boxes next to the com ports that are actually defined on your system and click on Apply to clear the other com ports.

This should be a temporary workaround until we receive an updated version of the FlexVSP driver.

Almost. The vendor that supplies the driver has it fixed (verified by us) and the driver is undergoing WHQL testing as I write this. Once we have a certified driver, we'll integrate it into a new version of SmartSDR and release it immediately. What is the ETA for that? Hopefully, it will not be more than several weeks. It really is out of our control at this point.

The program to fix the registry warns one running Window 10 the word is 256 bits in length and will be overwritten with a 32 bit. Can one let it overwrite and then make the obvious adjustment to 256 bit? Bits / hex / regedit doesn't scare me!
